format xml data for output

[bksella sella]

Hi

I have the code : xmlelement("cognome",dn_cognome) which returns xml data of xmltype. I am storing the returned value in a variable. I am not able to display the returned xml data using dbms_output.put_line function in my pl/sql block. Can anyone pls give me a solution to this. Do i need to format the returned value before displaying...if yes, how ?

Thanks in advance.
